Latent heat is energy released or absorbed, by a body during a constant-temperature process, for example a phase change of water from liquid to gas. This is written as: Sensible heat = (mass of the body) * (specific latent heat) The equation is Q= m L We have: Q: Latent heat m:...
Latent Heat Formula The latent heat formula shows that the latent heat is generally computed by dividing the energy needed for the phase change by the mass of the substance that has gone through the phase change. The latent heat equation is the following: {eq}L = Q/m {/eq} Where:...
Thus, when we add heat to a liquid, we are actually causing the molecules to vibrate. The latent heat will be the energy required to change the molecular movement. Each substance has a unique latent heat value. The Formula for Latent Heat: L =QM Where, Q = amount of heat M = mass ...
The latent heat of fusion is equal to the energy absorbed or released during a phase transition divided by the mass of the substance that is either melting or freezing. The latent heat of fusion formula is: Lf = q/m It can also be written as q = Lf m How do you calculate the...

Latent heat calculation All we need to know to compute the latent heat is the amount of substance and its specific latent heat. The formula is: Q=mLQ=mL where: m [kg]m [kg]— Mass of the body; L [kJ/kg]L [kJ/kg]— Specific latent heat; and Q [kJ]Q [kJ]— Heat absorbed ...
Calculation of Specific Latent Heat of Fusion: Once the ice has completely melted, calculate the specific latent heat of fusion using the formula: ,Where: is the heat energy absorbed (in joules), is the mass of the melted ice (in kilograms), ...
